There was multiple bridges hit,was only sure of the 3 I mentioned.That's the eastern way into Crimea. Going via the western route is a long way round.
These just go over the Crimean Canal, which is now drying up, so not actually that much if an obstacle. It does however make it difficult to supply the eastern side of the canal from Crimea without bridging equipment.
Taking out the other bridges on the canal going north to Nova Kakhovka would make it difficult for Russia to supply the Zaporizhzhia front from Crimea snd would make it difficult to move reinforcements back to a drying east/left bank of the Dinipro.
11 other bridges go over the canal to the east of main roads going north:
Stavky, Kalanchk (E), Kalanchk (N), Mykolavia, Brylivka, Yuvileine, Shchaslyve, Serhiivka (T2206/T2210 junction), Tsukury (T2202/T2210 junction) and Tavriiis'k (T2202/P47 junction)
All would be taken out if Ukraine crosses Dinipro as Russia has kindly withdrawn forces to support the Zaporizhzhia front.
The Chongar bridge,the equipment was being brought over by ships,which made it quite easy for supply to Donetsk and Zaporizhzhia Regions.
Not anymore.
